Kalanchoe plant named ‘2000-0716’

ABSTRACT

A distinct cultivar of  Kalanchoe  plant named ‘2000-0716’ characterized by its upright plant habit; deeply lobed dark green-colored leaves; large red-colored flowers; and excellent postproduction longevity.

Botanical classification/cultivar designation: Kalanchoe blossfeldiana cultivar 2000-0716.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Kalanchoe plant, botanically known as Kalanchoe blossfeldiana, and hereinafter referred to by the name ‘2000-0716’.

The new Kalanchoe is a product of a planned breeding program conducted by the Inventor in Hinnerup, Denmark. The objective of the breeding program was to create new freely-flowering Kalanchoe cultivars with large flowers, attractive flower coloration and excellent postproduction longevity.

The new Kalanchoe originated from a cross-pollination made in Hinnerup, Denmark, of the Kalanchoe cultivar Yellow African, disclosed in U.S. Plant Pat. No. 12,299, as the female, or seed, parent with the Kalanchoe cultivar Red Jaqueline, disclosed in U.S. Plant Pat. No. 12,300, as the male, or pollen, parent. The new Kalanchoe was discovered and selected by the Inventor as a single flowering plant within the progeny of the stated cross-pollination grown in a controlled environment in Hinnerup, Denmark.

Asexual reproduction of the new Kalanchoe by terminal cuttings taken at Hinnerup, Denmark, by the Inventor, has shown that the unique features of the new Kalanchoe are stable and reproduced true to type in successive generations.

BRIEF SUMMARY OF THE INVENTION

The cultivar of 2000-0716 has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, daylength and light intensity, without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘2000-0716’. These characteristics in combination distinguish ‘2000-0716’ as a new and distinct cultivar:

-   -   1. Upright plant habit.     -   2. Deeply lobed dark green-colored leaves.     -   3. Large red-colored flowers.     -   4. Excellent postproduction longevity.

Plants of the new Kalanchoe differ from plants of the parent cultivars in petal coloration and postproduction longevity.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying colored photographs illustrate the overall appearance of the new Kalanchoe, showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photographs may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Kalanchoe. The photographs were taken under diffuse natural light conditions on an overcast day at approximately noon in Hinnerup, Denmark.

The photograph at the top of the sheet comprises a side perspective view of a typical potted plant of ‘2000-0716’.

DETAILED BOTANICAL DESCRIPTION

In the following description, color references are made to The Royal Horticultural Society Colour Chart, 1995 Edition, except where general terms of ordinary dictionary significance are used. Plants used in the photographs and for the following observations and measurements were grown in Hinnerup, Denmark, under commercial practice in a glass-covered greenhouse for about 10 weeks after the start of short day/long night photoperiodic treatment with average temperatures of 20° C. Plants used in the description and photographs were not pinched. Unless otherwise specified, the leaf description represents leaves from a vegetative plant.

-   Botanical classification:     -   -   Kalanchoe blossfeldiana cultivar 2000-0716. -   Parentage:     -   -   Female, or seed, parent.—Kalanchoe blossfeldiana cultivar             Yellow African, disclosed in U.S. Plant Pat. No. 12,299.         -   Male, or pollen, parent.—Kalanchoe blossfeldiana cultivar             Red Jaqueline, disclosed in U.S. Plant Pat. No. 12,300. -   Propagation:     -   -   Type cutting.—Terminal cuttings.         -   Time to produce a rooted young plant.—About 14 days.         -   Root description.—Numerous, fine, fibrous, and             well-branched. -   Plant description:     -   -   Form.—Upright plant habit with numerous compound cymes;             freely flowering. Actual plant shape will depend on whether             or not plants are pinched (apical terminals removed).         -   Branching habit.—Freely branching. Pinching (removal of             terminal apex) is not required but will enhance lateral             branch development.         -   Plant height at flowering.—About 38 cm.         -   Plant diameter at flowering.—About 35 cm.         -   Foliage description.—Arrangement: Opposite, simple. Size:             Leaf size is reduced after floral induction. Vegetative             plants: Length: About 22 cm. Width: About 18 cm.             Reproductive plants: Length: About 10 cm. Width: About 8 cm.             Shape: Deeply lobed. Apex: Obtuse. Base: Cuneate to             truncate. Margin: Crenate. Aspect: Slightly concave.             Texture: Glabrous, leathery; succulent. Color: Developing             foliage, upper surface: 146A. Developing foliage, lower             surface: 146B. Fully expanded foliage, upper surface: 147A.             Fully expanded foliage, lower surface: 147B. -   Flower description:     -   -   Flower type and habit.—Single flowers arranged in compound             dichasial cymes that arise from leaf axils. Upright             flowering stems. Freely flowering.

During             the winter with supplemental lighting and 20° C. growing             temperatures, about eleven weeks of short day/long night             conditions are required to produce flowering plants. Time to             flower is primarily dependent upon temperature and light             intensity.         -   Flower opening.—First flower open is the terminal flower at             the main axis and is followed by the operating of the             terminal flowers of the side branches of the inflorescence.             About 1.5 weeks after the first flower has opened, 50% of             the remaining flowers are open.         -   Post-production longevity.—Plants of the new Kalanchoe             maintain good leaf and flower substance for at least five             weeks under interior environmental conditions.         -   Flower diameter.—About 2.5 cm.         -   Quantity.—Freely flowering, at least 100 flowers per plant.         -   Flower buds.—Shape: Narrowly oblong.
